Wheel nuts
Low nut.
High nut.
There are two different types of wheel nut,
depending on whether the wheels are steel or
aluminum.
Steel rims – low nut
Steel rims are normally secured using the low
type of nut, although steel rims may also use
the high type.
Never use the short type of nut for alumi-
nium wheels. This could cause the wheel to
come loose.
Aluminum wheels – high nut
Only the high type of nut can be used for alu-
minum wheels. This is considerably different
from other types of nut because it has a rotat-
ing conical thrust washer.
This nut can also be used on steel wheels.
Lockable wheel nut
If steel wheels with lockable wheel nuts are
used in combination with wheel covers, the
lockable wheel nut must be fitted to the stud
nearest the air valve. The wheel cover cannot
otherwise be installed on the wheel.
